Surface modifier T-402(TDS)
1、Descaription
T-402 is a special surface modifier for powder coatings,whichcan effectively reduce the melting viscosity and surfacetensionofthe system, greatly reduce surface defects, and improve thesaltsprayresistance and boiling resistance of the film.
2.Typical physical data
| Appearance | White powder |
| Melting process temperature(℃) | 130～135 |
| Solid content(%) | ＞99% |
3.Suggested formulation
Internal extrusion 0.5-1.5%;
4.Purpose:
1、Eliminate orange peel and improve the fullness and smoothnessofthesurface.
2、Degassed and resistant to yellowing, suitable for thick coatingofhydroxyalkyl amide system.
3、It is easy to take off the film during printing and transfer.
4、Improve the storage stability and powder loading rate of powder.
5、Improve salt spray resistance and boiling resistance.
6、Improve the compatibility between polyester and eliminate surfacefog.
